These sites don't do an adequate job of informing the public of their inability to obtain accurate and up-to-date information. These sites are businesses. If they advertised the truth openly to every visitor about where they obtain their information then fewer people would visit and their revenue from adds and a lead service for Realtor's would dwindle.
There is nothing wrong with these sites trying to provide a service the public desires (i.e. housing information without the use of a knowledgeable individual). The problem comes due to their lack of explaining the true accuracy of what they provide. Full disclosure is not in their best interest. Nowhere on the page above does Trulia state that values may not be correct or accurate and to contact a local Realtor. Heck, your website and mine provide better value IMO than Trulia and Zillow since we have access to HAR data.

Here is the truth. Kevin, how can they put information out there like that, if it is not listed anywhere? To get people to inquire. It is not right.
Mr. Nguyen, please use http://www.har.com or http://www.garygreene.com for update listings.
You can call me also.
This home was sold and very close to the original list price.
If you are seeking the latest listings and tax information the Houston Association of Realtor's website is the best place to visit.
